Hi, I just uploaded tftpd32, and i have a file. i want to upload this file to tftpd32 server programme then i want to learn ip of tftpd32 server?Could you please help me?

I'm afraid that this doesn't make much sense, to me. Whatever computer you uploaded TFTPD32 to, that will be the "TFTP server." That server has to be running TFTPD32 in order to actually service TFTP requests. Go onto the server computer and run TFTPD32. Inside, you will find the IP address. Look at the Server interfaces field in the program.
